of tape by hand, the ends of the strips being tied or knotted. sarilv slow.

'lhe object of the present invention is to provide an automatic machine for applying and fastening the bail tapes to the bodies of receptacles o'l various kinds, the invention This operation is necesbeing. however. especially applicable to the manufacture ot' ice cream boxes which are made of paper and having carrying bails composed of strips of tape.

The invention is illust 'ated as embodied in a machine which supplies the body receptacles in the -form of llat paper blanks, one by one. to mechanism which automatically cuts strips of tape from a reel or roll, carries the two ends of each strip through apertures in car-h blank, and glues said ends to secure them in. place; all this being done before the blanks are folded up to make boxes or pails.

The machine illustrated has developed a speed oil? production of nearly 1,000 an hour, and has been designed to supply blanks, with attached tape handles, to the folding machine described and claimed in my application lTShlZT, tiled February El, 1909. I

wish to he understood. however, as not limit in: myself to the production ol' ice cream boxes or pails. since the mechanism for applying and fastening the strips of tape may be emploved in connection with blanks suitable for other kinds of receptacles and made of other kinds of n'iaterial than the kind of paper of whichice cream boxes are usually composed. 'lheret'ore the term blanks as employed in the description and claims, is to be understood as used. for purposes of description only, and not as a limiting term.

Similar rei'lerence characters indicate the same or similar parts in all the figures.

The frame of the machine comprises side members 25 supported by suitable legs 26 and connected together by two transverse tie bars 27 and certain rods and shafts hereinafter described.

hising from the frame at one end are two standards 28 which support the primary feeding mechanism.

The blank support or hopper comprises an inclined table 29 rigidiy mounted on brackets 30 securedto a rod 31 the ends of which are gripped in split bearings 32 at the outer ends of two arms 53 the inner ends of which have split bearings 55% clamped on a rod 35. To guide blanks of varying widths on said table, I provide side guides 36 which rise from the top of the table and are adjustable laterally as by pins 37 projecting from the outer sides of the guides and through blocks 38 secured to the sides of the table, set screwsZ-BQ holding the pins and the guides in their laterally adjusted positions. The blanks are fed singly from the top of a pile on the table, by intermittentl y operated friction roll feed mechanism to a pair ofpositively driven nipper rolls as hereinafter described; to secure the best results in spite of different kinds and conditions of blanks, it is desirable that the angle of inclination of the table may be conveniently adjusted without altering the relationship of its lower end to the friction feed roll, or to vary thatrelationship, or to change the distance between the table and the said nipper rolls. These various adjustments may be effected by the following structure :-T he rod 31 is connected by links 40 with a rod +11 mounted in the upper ends of two uprights 4-2 (Fig. 9) adjustably secured, as by set screws %3, on the inner ends of two rods .44 which are mounted in the standards in alinement. The intermitte'ntly actuated friction feed roll is secured to a shaft 46 mounted in bearings provided in the links :h), and the shafts 47 of the continuously driven nipper rolls in are mounted in the standards :28, one shaft being preferably mounted in sliding blocks 49 yieldingly acted on by springs 50 which may be adjusted by set screws 51. It will now be understood that, by loosening and tightening the various split bearings and set screws described, the table -may have its angle of inclination changed, and its lower end may be set more or less under the feed roll, and the table and feed roll can be set at the proper elevation above. the nip of the rolls 18.

In order that the space for the cjcction of the single blanks may be varied to suit varying thicknesses of material, and to compensate for wear. so that no blank can slide down the, table until fed by the roll 45 l preferably provide the lower part of tlie tablewith one or more adjustable blocks which are, desirably. of rubber. in Fig. 5 the loweuend of the table is indicated by dotted lines as cut away to form an opening to one end of a shaft of).

or recess through which the blocks 5:2 project. Each block is mounted in a holder 525 (Figs. f and 35) carried l a plate 54 which is guided on a pin 55 rising from a colr'r 51S adjustably mounted on rod Ill and tically adjusted by a screw 57 lilting a threaded bearing in said collar. The reasons for employing blocks 52 of rubber or equivalent nuitcrial is to provide thc necessary friction to prevent a thin blank sliding down the table. And the reasons for pro viding two blocks which are. iinlc n-mlently adjustable is tln t the retarding effect should be either by a wide surface or in at least two laterally separated locations. As it is dillicult to cut rubber squarely, and as it frequently wears away unevenly, the provision of the two adjustable hold-back members 5;! enables the ma'liine. to always present, in operation, ellicient means for preventing the sliding down of a thin blank, or the distortion of a blank out of a straight line of feed by the roll is). If the roll could act along one line on the blank \\llll, a single hold back acted along-a different line, there would be a distortion of feed which is prevented by the two blocks sidc by side. Another rcason for providing two adjustable blocks 1- Is that the feed roll 45 is preferably made in two sectirns which may be set more or less apart on the shaft lb according to the idlh and specific shape of the blanks. sections of the roll are spaced apart, the io tarding blocks should be correspondiugly spaced by adjusting the collars 56 along rod 31.

The means for intermittently actuating the feed roll shaftlb comprises the follow ing devices and connections: A ratchet SS is secured to the shaft 46, and said ratchet is engaged by a spring hcld pawl 59 carried by a collar 0 loose on said shaft and having a pinion 31. A rack 32 is held in mesh with said pinion by a guide (33, said rack being conncctcd with an arm bl of a rock shaft U5 which is mounted in hearings at the upper ends of the standards 28. The rock shaft .has another arm (Sb which is connected by a,

rod 37 lo a strap on an eccentric os secured The other end of said shaft has a gear TU meshing with a pinion Tl on the main power shaft T2 hav iug a bcll wheel T3. The arm (ii is slotted for the connection of the rack bar 32 so that the amount of throw imparted to the rack may be varied and consclpiently the amount of rotation given to the feed rolls may be a cording to the length of blanks beingfcd.

'lhc nippcr rolls have intcrmcsbi ig pin-- ions, the lower one of which meshes with a gear T-i carried by a stud shaft having a pinion T5 meshing with the gear T and said nippc-r rolls are consequently rotated continuously ready to take each blank as it is fed from the table and ad mice or forward lift) hand if desired.

Of course the other lllli h) may have a stud for another brake The upper (and of the oo is ttachcd to the stud T7 in such manner that, by, rotating the stud and securing it as by a nut 78, the loop may be wound up on the stud toincrease the binding of the other end of the loop on the feed wheel shaft.

To properly direct the blanltsfrom the primary feed and nippcr rolls to the lioriacontally acting secondary feed, Vi'illClh car ries the blanks in properly spaced l'filfltfifil'lship the devices for further treatmentof the blanks 1' provide curved guides or iiug'ers 79 which ora secured to a rod 80 which in turn, secured to the standards 11 war the bases thereof;

I a. lose boo, oiipai is a slow rotation to the shaft 107 and the .two glue wheels 106 in the direction of the arrow in Figs. 5 and 7 to presentfreshly coated surfaces to the action of the transferners which convey glue to the small .pads which'place small spots of glue on those. portions 01' the blanks where therends of the tapes are to be later placed. Asthe two mechanisms are alike, :1 description of one will sufiice for both. Each transferrer coinprises a small roll. 123, preferably of rubber or equivalent yielding material, mounted on a pin 124: projecting from a block 125 mounted to reciprocate in horizontal ways formed in a bracket 1% mounted on a tie rod 127. The pin 124 passes through a slot in an arm 1:38 depending from a rock shaft 129 said rock shaft having an arm 130 provided with a roll which is actuated by a cam 131 on the shaft 117. One or more springs I 132 normally hold the roll of arm 130 in contact with the cam-131 and the transferrer rolls in contact with the glue wheels 106. The object of the horizontal ways for the transferrer rolls is to insure the proper path of travel thereof under the flat undersur-' faces of the pads Each of said pads is carried at the lower end of a pin 131 mounted to slide vertically in a bracket 135 adjustably secured to a vertically movable rod 136. The pin is yieldingly held in its lower position by a spring 137, the limit of lower position being adjustably determined by one or more set nuts 138. The padcarr-ying rod 136 is supported at its ends in slides 13?) mounted in vertical ways in the standards 101, said. slides having pins entering slots in arms 140 of a rock shaft 141, the latter having another arm 112 provided with a roll and actuated by a cam 143 on the shaft 11.7. One or more springs 14-1 hold the pad-carrying rod 136 in a plane so that the pads will be well above the path of the blanks and in a plane to permit the transferrer rolls 123 to pass under and coat the bottoms of the pads with glue. The cam 14-3 acts however at the proper times to depress the slides 13!) and the pads so that the latter will deposit small patches of glue upon the blank below. To support the blank against the pressure.- of the pads, I provide small tables 145 secured to the rod 127. Each table is formed with arecess l ltl (Fig. 12) so that, if no blank should be over the two tables when the pads descend, no glue will be deposited. The pads do not descend far enough to contactwith the bottoms of the recesses. but only far enough to press on blanks supported by the edges of the tables.

It is desirable that each blank shall be temporarily arrested in the cxact position for receiving the spots of glue applied by the pads. The proper location for said spots of glue is indicated at a a in Fig. 15, close to the slits a through whichj the ends of the tapes are to be passed by the mechanism later described. The secondary feed belts do not grip the bl'pnks at this point so tightly as to prevent slipping if the blanks are positn l stopped. 'loeti'ect the tenmorary slo jipagc of each blank, 1 protide two fingers ll having their shanks 14S adjustably more. in blocks 145 which are themselves adjustably mounted on a vertically movabl car-- rying rod 150. 'lhese lingers can be so adjusted as to engage the advancing cdgc of a blank at two points, regardless of the shape of said edge. and hold the blank while the belts continue to travel and during the operation of the glue pads. The linger car rying rod is supported at its ends in slides 151 mounted in vertical ways formed in brackets 15? carried by the side members, of the frame each slide being depressed by a spring 153 and having a roll 15-1 at its lower end riding on a cam 155 secured to shaft 120. The two cams 15.3 and the springs 153 control the movements of llic rod 150 so that the fingers 147 are interposial in the path of the blanks at the proper tinn-s. and long enough, for the pads to apply the spots of glue. As soon as the lingers rise. the blanks are again moved by tho secondary feed belts to the devices which cut oil a strip of tape of just the right length. and insert its ends through the slits a. of each blank, and fasten the ends down on the spots of glue.

It is sometimes desirable. when wide blanks are to be taped. to provide supports for the wings or side portions of thc l)l:\1llt Such supports may comprise wires 1m; s'iie ably supported at their ends. There are also two sets of adjustable side edge guides 157 L-shaped in cross section. each having a flaring entrance end. vll: h of'these guide is carried by a pin 1.38 projecting from a block 159 adjustably secured on tie rod 127. The. other set of guides consists of a pair of elongated vertical plates 1(30. each carried at the inner end of a rod 161 adjnstably mount ed in a bracket .162 secured to a side member of the frame. Each plate 160, at the end nearest the gluing devices. is curved outwardly. and at its-other end has a horizontal flange 163 which is inclined upwardly in the direction of travel of the blanks to insure the proper entrance of the entire blank to the taping mechanism. This mcchanism is supportial on cross bars lli-l. by means of up rights 165. the bed frame of the mechanism being indicated at 106. The top plate 1'37.

over which the blanks pass. is suitably sup- 1 176 in arresting position across the plane of movement of the blank to hold said blank stationary long enough for the tape ends to be applied through slit-s of the blank, and then release the blank to permit each to be carried forward again'by the continuously operating upper belt 86, the blank being, of course, between the top plate 167 and said belt 86, i

The main shaft 173 is provided with a sprocket engaged by a chain 177, (see Fig. 2). Said chain is mounted on a sprocket carried by a shaft 178, havin a gear 1T9 meshing with a pinion 180, carried by a stud shaft mounted in one of the side members of the frame, and having a bevel pinion 181, meshing with a bevel pinion, 182 on the shaft 81. The stud shaft carries also a gear 183 which meshes with a pinion 184 on a shaft 195, (see Fig. 4), said shaft 185 having a gear meshing with a gear 186 on the shaft 95. (see Fig. v

The top plate 167 is formed with a trans verse opening as best shown in Fig. 2, or is otherwise formed. to permit the operation-of applying the'tape, as hereinafter described. To prevent the blanks from catching on the far edge of said opening, I may employ thin guide strips 187 crossingthe openin r. To guide the edges of the blanks, I employ guides 188, each having a slotted side arm 189, through which a set screw 190 passes to secure the guide to the plate.

ln order that the pressure of the belt 86 on the blank on the top plate shall be greater when the arresting fingers move to the position shown in Fig. 4 than when said lingers are down to arrest the blank, 1 provide one or more pressure rolls above the operating; stretch of said belt, which roll or rolls will be automatically raised and lowered. One of such rolls is shown in Fig. 4 at 191,-a1r other at 192. The roll. 191 is carried by am arm 193, mounted loosely on the cross rod 194*. The other roll 1972, is carried'by "an arm 1% of the rock shaft 195 mounted in. bearings provided in uprights 19f) rising from the bed 166. At one end (see 2) said rock shaft is provided with an arm 197 which is actuated by a cam 198 at the end of the shaft 173. The rock shaft 1%. has another arm 199, which is connected by a. link 200 to an arm 193. These connections are such that the rock shaft is acted. upon at the proper time by the cam 198, to lift the roll 1% justas the arresting fingers 17G move downward. find the connections described also cause the roll 191 to be lifted at the same time. The necessary pressure of the rolls may be cli'ccted by means of a spring 201 connecting a pin of shaft 195 to a lixed point provided by the top plate (see Fig. Preferably said top plate is provided with. slots or small openings, in which are suit ably mounted rolls 202, (see Figs. 4- and directly beneath the rolls 191., 192, so that theblauk under the belt 86 will not be held. back by friction with the top plate wl'ien the blank is to be advanced.

The upper stretch of the belt 86 passes under an idle roll 203 mounted on the cross rod 19-1 (see Figs. 1 and 4c). The said belt may be kept at the proper tension by one or more rolls 204 carried by adjustahly mounted arms 205, one of said arms 205 ed on cross rod. 194:, and the other cross rod ll hile each blank is held, in. arrested position, on the top plate, the two ends of a length of tape 6 are tucked through. the slits a, and pressed dow'vn on the spots of glue by tuckcrs or inserters, the passage of which is permitted by the shape of the slits of, said shape being such that tongues formed in the blanks, said tongues yielding as shown in Fig. 20, when the inserters pass through. This involves novel structure of blank and box matter of another application for patent. When the blank is folded. as shown in l i 16, by the machine claimed. in..1ny application 479,827 hereinbefore referred to, the portions which carry the glue and have the slits a are shielded by other portions of the box. In other words, the ends of the bOK other on an are composed of double walls with unslitted portions covering the inside surfaces of the slitted walls so that the contents of the box can not come incontact with the glue, or the tape ends, or escape through the slits= The top plate is omitted from 17, to show the mechanism for drawing a length of tape, cutting it off, and inserting its ends through the slits a. Two guide rods 207 are supported by the blocks 168, (sec 17) and pass through a. center block 208 the top of which is in a plane to firmly support the central portion of the front ed go of the top plate, Mounted on the rods are two slides 209, 210, each. connected by a link 211, (see Fig. 2G) with the outer end of a lever 2152 pivoted on a post 2123 rising from. the bed 1%, (see Fig.5. lligid with each lever 212 is an arm 5314 connected. bv a link with the upper end of angle lever 21%. The slide of the links 215 have universal ioint connections with the arms 21% and levers 216. Each lever Q16 bei n g mountwhich form the subject.

pivoted at 217 and has a roll 218 bearing on a cam. 219 carried by shaft 178. Each lever is moved in opposition to its actuating cam by a spring 220 coiled on post 213 and having one end fixed and the other end connected to arm 2H. The two levers 212 are actuated by their cams and springs to move the slides209 21d simultaneously toward and from the center block 208, to measure oil the length of tape to be attached to each blank. The cams 219 act to move the slides toward each' other and the springs 220 not to move the slides apart. 'lherefore by adjustablylim'iting the outward movements of the'slides, the length of tape is determined to suit different sizes of blanks. I have illustrated (see Figs. 17, 23 and 27) collars 221 which surround one of the guide rods 207 for thispurpose. said collars being carried by, and adjustable with, the post supporting blocks presently described.

The slide 209 (see Fig. 26) has a fixed top plateor jaw 222 and below it a pivoted Hod-a.

gripper or jaw 223 having a cam-shaped or ply not shown, between the jaws 222, 223,

and when the slide 209 moves in the direction of the arrow near it in Fig. 26 it pulls the tape along with 'an end projecting to transferred to and grasped by the nipperjaws of slide 210.; The top jaw 226 of this slidev is fixed and transversely corrugated.

- The coactiiig lower jaw 227 is also transversely corrugated and is carried by a vertically movable plunger 228, pressed upwardly by spring 229. The lower end of the plunger is reduced and projects below the. bottom 23.0 of the socket portion of the slide and has pivoted thereto a lever 231 havinga heel 232. A. spring 233 holds the lat-ch normally in theposition shown in Fig. 26.1 In said Fig. 26, the two slides have not reached their positions of close proxiin-ity; but as they continue. to' advance toslide 209 may enter between said jaws.

ward each other, the contactof the tip of latch 231 with a fixed hi 23% causes the heel 232 to fulcrum against the bottom 230 in such manner as to'pull the plunger down and rides over lug 23-: without opening the jaw 227 so that the tape is drawn across the machine, the pivoted cam-shaped aw 223 ating cam 2-17.

of slide 209 permitting the tape to run quite freely in this direction. said slide of course, at the same time, moving baclnvardly. As

described, the arms 212 actuate the grip-' pers carried by slides 20!). 210. so that they simultaneously approach the longitudinal middle or center of the machine at which point the block 208 (Fig. 2b) is located. Of course, when the gripper blocks return, they simultaneously move away from said middle or center. (Inc gripper pulls the tape from the source of supply, and the other gripper takes it from the first gripper. and. consequently. each gripper has to travel but onehalf of the distance that would be required if one gripper were to do all of the pulling otl from the source of supply. Owing to this fact that the two grippers move toward and from each other. one having means for pulling tape from the supply. and the other having means tor taking the tape from the first one. the operation of the machine is much faster than if one gripper were to be relied upon for doing the entire pulling and measuring. In Fig-17 the tape is not shown as extending between the jaws of the slides becausethat figureis drawn to show the positions of the parts an instant later. when the tape has been'cut and the cut length has been shifted slightly aside by mechanism presently described. The cutter which severs the tape near the jaws of'slide 209 will be described in detail after first explaining the mechanism which transfers the length of tape to position to have its ends tucked through -the slits of the blanks. hecause the act of gutting occurs after the conimencement of the transferring motion.

Each of said blocks has a hearing 2255) for an upright post 240 having a pin .241 at its upper end. The, pin is a wide one merely for strength. one edge being in line with the axis of the pin so that whcn the ends of the tape are carried around .said pins as presently described. there will he no material change in the lcngtlnvise strain on the tape.

When the return movement begins, the tip of the lever 2'66 engages the inner end of lug 269, and the said tip of the lever is thereby retarded, so that continued movement causes the lever to oscillate and positively actuate the blade 5264, so as to cut the tape, this operation having been just performed when the parts reach the position shown in Fig. 17. Fur-the; movement of the posts and their arms and grippers toward the position shown in Fig. 1S 'vill cause the tip of lever 266 to ride over the top of-lug 269, the shears remaining closed until again positively opened by the opening movement of the grippers as the parts return to cutoff and grip a new length of tape.

When the cut length of tape has beencarried to the position shown in Fig. 18, it is in position to have its ends inserted through the slits of the blank, and I will now proceed to describe the mechanismfor doing this. As shown in Figs. 17, 18 and 22, the bed frame 166 is provided with two standards, 27%, in which is mounted a rock shaft 275, the ends of which are tubular, to receive extensions 276, the outer ends of said extensions carrying curved fingers or inserters 5277. The extensions 276 constitute practically parts of the rock shaft, but they are adjustable in the hollow rock shaft so as to space the fingers 2T7 relatively to each other, according to the width or size of blank that being taped. The extensions are splined in the portion 275, and may be held in their longitudinal adjustments by set screws278. The portion 275 of the rock shaft is provided with an arm or arms 279 to which is 3;:ivoted a link 280, the other end of said link being connected to a lever 281 pivoted at 9.82, and having its lower end in the path of the cam 28? secured on shaft 173. The timing of the operation of cam 283 is such as to rsarillate the rock shaft so as to cause the urverl fingers 277 to move upwardly against a under sides of the tape near to the points where the ends of the tape are held by the swinging jaws in the position shown in Fig. 18 and pull the ends out from the jaws and carry said ends up through the slots in the blank. as'shown in Fig. 20. It has been mentioned that the corrugations or teeth of the tape-shifting jaws extend transversely of said jawsl This enables the tape ends to be pulled out from thefgripping jaws by the fingers QTL-because the direction of pull, ien doing so, islengthwise of the corrugais or teeth. I

.he return movcn'ient of the rock shaft is tlected by a spring, such as shown at 284 in said spring being connected to the and toa fixed point of the frame. .z-oeration ofthis part of the mechan sm, the fingers 277 move from the position si ially thatshown in Fig. 19, to a point a little beyond that shown in Fig. 20.

T92 is at the rear of said shaft.

As said fingers pull out the ends of the tape from the gripping jaws, they tuck or insert said tape ends through the slots of the blank, which, at this time, is arrested, the ends of the fingers 277 moving to a point far enough to press the ends of the tape firmly down upon the spots of glue which have been applied to the blank near the slots a. This often results in some glue adhering to the ends of the fingers: I employ devices for keeping the ends of the fingers clean, and said devices will be described hereinafter.

Immediately after the fingers 277 have pulled the tape ends out from the gripping jaws, said jaws begin to return to the position shown in Fig. 17, to take a new piece of tape. I will mention here, that to adjust this portion ofthe machine for different widths of blanks, it is only necessary to adjust the blocks 237, 238 by means of their.

bolts, the heads of which are in the bed groove 235, and to then correspondingly adjust the rock shaft extensions 276. There are, however, above the top plate 167, some pressers which also need to be correspondingly adjusted. 2 and 4) comprise arms 285, which are socured to the rock shaft 195, and may be adjusted longitudinally thereof. It will be noticed in Fig. 4 that the arms 285 project forwardly from the shaft 195, while the roll Therefore, the arms 285 are raised when the roll 192 and the roll 191 are-depressed. And of course, when said rolls are raised. the arms 285 are depressed. This occurs at the same time that the fingers 176 arrest the movement of the blank. an elastic foot or pad 286 to bear upon the blankand press the blank on the top plate. This pressure occurs beyond the'edges of the conveyer belt 81), and the blank is thereby held against any possible shifting by the operation of the inserting fingers 277. Each arm also has a bifurcated finger 287 having a grooved or rounded end surface to bear upon the blank on each side of the slot through which the inserting finger passes.

After the ends of the tape have been inserted as described. and tacked by the ends of the lingers pressing the tape on the spots of glue, the arresting lingers 176, and

These pressers. (see Figs.

Each of said arms has the pressers described release the blank, and

it is started forward, and its under surface acted upon by an endless belt 288 (see Fig. said belt being mounted on a pulley 289 secured to shaft 185 and on a. pulley 290 mounted on a cross rod 291. Preferably the upper stretch of the belt 288 is supported bya plate 292, and firm cooperation he tween the upper stretch of belt'288 and the lower stretch of belt 86 is secured by a roll 21) having its carrier niounted in a. bracket 29+, adjustably secured on an arm 295 which is rigidly supported by the cross rod 206.

The carrier of the roll 293, is yieldingly pressed downward by a spring 296.

.The belts 86 and 288 deliver the taped blanks from the machine, but it is desirable that the portions of the blanks to which the tape ends have been tack/ed shall be subected to considerable pressure, to cause the tape ends to be firmly secured. Asshown rolls may be simply idly mounted in their yokes. The upper rolls 300 are'secured to ashaft 301, said shaft having a sprocket 302 at one end, said sprocket bemg driven by a.

chain 303 from a sprocket on shaft 95. The

relative sizes of the pulleys and sprockets "are such that the peripheral speed of the rolls 300 will be substantially the same as the speed of the belts 86 and 288. to the pressure exerted on the blank as it passes between the rolls 220T and 300, the upper rolls are liable to become coated with glue which is on the upper surfaces of. the blanks. To keep the rolls 300 clean, preferably employ both scrapers and wipers. The scrapers 304: have their shanks 305 adjustably secured in blocks 306 adjustably secured to the cross rod 307. These scrapers are preferably inclined, so that glue scraped oil" thereby will be deflected beyond the edges of blanks traveling underneath.

The wipers comprise wicks 308,'the ends of which are held in contact with the sur faces of the rolls 300 by means of flattened tubes 309. Each wick 303 restsin a reservoir or pan 310 siiapported by the cross rod 295% ater is placed in the pans to. keep the wicks and the rolls 300 moist, so that the glue can be readily scraped oil by the scrapers 301i. Of course the wicks aid. in keeping the rolls clean by the wiping action. in Figs. 17 and 36, 1 illustrate means-for keeping the ends of the inserting fingers 21" 7 free from accumulations of glue. The under surface of each. of the blocks 237, 238

formed with ways for aslidc 311, having an adjustable extension 312. The projecting end of. each slide 311 is provided with a post 313, which supports a water reservoir 31%, the latter having a wicktube 315, provided with an aperture 310 in one side. The eX- tension 312 is provided with a downwardly extending pin 317, said pin passing through a. slot in alever 318, pivoted at 319 to a fixed portion. of the machine, and having the'othei; endin position to be actuated by a ca1n320, formed as a protuberance from the end of cam 2&7. A spring connects the two lovers 313 so as to operate the slide 311 in opposition to the two cams 320.

The cams- 320 are so located as to ac 'uate the levers and cause the slides 311 to move Owingoutward and return ,during the time that the inserting fingers 277 occupy the position shown in Fig. 19. Suihcient of the Wick projects through the apertures in the wick tubes to wipe the tips of. the fingers and keep said tips moist.

All of the parts which require adjustments for different sizes of blanks are provided with means to permit such adjustments to be made. For instance, the side guides 36 for the pile of blanks are adjustable by means of their pins 37, mounted in the blocks 38. The two members of the feed roll -15 are adjustable toward and from each other on the shaft 46. The glue boxes 104:

may be set in proper lateral positions by means of the brackets 103, which can be secured in proper positions on the tie rod 102.

The arms 128 can be adjusted on the rock shaft 129 and the glue spotters or pads are correspondingly adjustable along the rod 136, the tables'lelfi being adjustable along the rod 127. i

All the other parts requiring adjustmentsare so clearly illustrated as to require no further description thereof, than has been given in connection with the descr ption of their operations. understood that the relative timing of the operations of the different mechanisms is such as to cause them-to act in proper sequence.

The glue spotters or pads 133 are made of requisite area'to place suilicient glue upon the blanks, in the form of spots to securely hold the ends of the tape which are first And of course it will be tacked and then pressed firmly down in the manner already described.

I employ the term tape for purposes of brevity of description and-not of limitation. Preferably the material is that which is commercially known as tape but need not necessarily be a strip of flat fabric. The term glue is also used herein for brevity of description and not of limitation, since any adhcsive'capable'of retaining the tape ends may be employed.
